Chris Brown did not admit he assaulted the alleged victim in his Washington D.C. criminal trial, says his lawyer.

The 24-year-old singer has been forced to spend 131 days behind bars after he admitted Friday in a Los Angeles court that he violated his probation by getting into a fight in Washington D.C. last year.

`When Brown admitted to a probation violation Friday in the Rihanna case, it did not constitute a confession in his assault case,` Brown's attorney Mark Geragos told tmz.com

He added that all Brown did was admit that he violated probation in Washington D.C. - he was not more specific.

According to the lawyer, there's no way the D.C. prosecutor could use Brown's admission as a confession, because the standard of proof in a criminal case is much higher than in a probation hearing.

He says he merely told the Rihanna judge it's "more likely than not" that Chris screwed up in D.C.

In a criminal trial, the prosecutor must show Brown screwed up beyond a reasonable doubt.

Even though Brown was ordered to serve another 131 days behind bars for the probation violation, with time served and jail overcrowding, he could get out in a matter of days.
